Really?  In that case, I don't understand Stefan's message saying that you can't
do that with Emacs.

You can easily use a face that has attribute `underline' and/or `overline' as a
text property or overlay.  And the line(s) can be any color.

(Like Eli, I too did (do?) not understand what the request is.)
